SHORE.

Application filed June 12, 1924.

The present invention relates to shores. The present invention will be described particularly with reference to the type of shore used in the construction of concrete 3 buildings, though as the description proceeds, it will be apparent that the invention is of much broader application.

In the construction of concrete buildings, it is the practice to shore up the false floor- 3 ing by means of anumber of uprights. Said uprights should be. adjusted so that their to as have a predetermined level. Various espedients have been used for leveling the tops of the shores, but many of said e1:- 1.? pedients lack the advantage of ready adjustability combined with the strength required to hold the concrete. after said concrete has been poured, or said expedients require the use of parts of rather special construction.

An object of the present invention is to provide an improved shore of simple construction which permits the use of timbers such as are commonly part of the equipment of builders.

A further object is to provide a shore which combines the advantages of ready adjustment with the advantage that timbers, as commonly provided by builders, may be utilized.

A further object is to provide a shore which permits ready and accurate adjust ment, which may be readily removed from place without danger, and which utilizes timbers commonly found in the equipment of builders.

A further object is to provide a shore which combines the-advantage of utilizing timbers, as commonly provided by builders, with the advantage that a non-slip gripping effect is had whereby the tendency to sag; under load is minimized. I

Further objects will appear as the description proceeds.

Referring to the drawings Figure 1 is a. side view illustrating one embodiment of the present invention;

Figure 7 is a fragmentary view of a modified structure preferred by certain users.

The numerals 101O indicate a pair of standards which may be held in spaced relation at the bottom parts thereof by means of the strap 11 which-is indicated as having a substantially U-shaped conformation, said strap 11 being fastened to the standards 1010 by means of bolts 1212. The standards 10 10 are held in spaced relation at their upper portion by means of the cast-- ing 13, which may be fastened to the standards 10-10 by means of bolts 14E14. The casing 13 and the strap 11 will hold the standards 10-10 securely in substantially parallel relation whereby said standards 10--10 will form guides for theslide 15. The slide 15 will preferably be of rectangular cross'section and it will be found convenient in the practice of the present in vention to use, for said slide 15, a timber having; a cross-sectional dimension, on each side, of four inches, timbers of this dimen sion being; common equipment of builders. The bracket 13 will be provided with a hole of sufficient dimension to permit free sliding movement of slide- 15 therethroun'h. Said bracket 13 serves as a guide for the. slide 15. I o

The upper portions of the standards 101O may be cut away on opposed faces and may be lined with members 1615 which may be bolted to said standards 1010. Mounted to have a free sliding movement between the linings 1616 is the casting 17, which casting 17 has the portion 18 engaging one side of the slide 15 and the portion 19 adapted to provide a housing for certain wedging members for abutting relationship with the opposite side of said slide 15. The casting- 17 is also provided withthe walls 19"19 which connect portions 18 and 19. Said walls 1919 embrace the slide 15, whereby casting 17 encircles slide. 15.

The portion 18 is provided with the offset member 20 which forms a seat for a. nut 21, which nut has screw-threaded engagement with the bolt 22. Said bolt 22 is supported by the off-set portion 23 of. the bracket 13. The ofi-set member 20 of the casting 17 will preferably be so formed as to provide a pocket for the nut 21 to prevent rotation of said nut 21. The headof the bolt 22 above the off-set portion 23 of the casting 13 will be so placed, however, that a ill) wrench may readily be applied thereto for the purpose of communicating turning movement. to said bolt 22. The portion 18 of the casting 17 will be provided with a pair of laterally extending lugs 2%2-l adapted to engage the adjacent side edges of the lining 1(31(3. The remainder of the portion 18, however, will preferably lie within the boundaries of the opposed faces of linings 1G-16.

Referring now to the housing 19=on tl e opposite side of the shore, said housing provided with a pair of lugs 25 adapted to engage the adjacent edges of the linings 1($16. Mounted with n the housing 19 is the metallic gripping memb r 26 having the oi'set lugs 2T-2T tor engaging with the upper side ot' housing" 1.9. One side of the gripping member 26 is provided with the horizontally extending; ribs 28-428. which ribs SIS-28 are adapted to dig into the adjacent face of the slide 15. and for this reason, the horizontal dimension of the gripping member 26 should. with the exception of the lugs 2T2T, be of less width than the space between the linings 16-46, or at least the ribs 28Q8 should be within the space between linings 1616 whereb said linings will not interfere with the gri 'iping action of member 26. The outer side of the gripping member 26 is provided vith the outstanding" stud 2f adapted to receive the wedge member 30. Said wedge member 30 is provided with the slot 31 within which the stud 29 is adapted to ride, and is also provided with the tapering portions 32-32 adapted to engage with an inner wall of the housing 19. The wall ot housing 1!), adapted to engage the tapering portions 3232 of the wedge member 30, will preterablv be tapered to conform to said taperin members 3232. Preferably, the stud 29 will be provided vith an enlarged portion 33 at its outer .xtremitv whereby to prevent loss of the gripping member 26 and wedge member 30 when the slide 15 is removed from between the standards 10-l(l.

The upper end of the wedge member 30 and the lower end thereot will pre'tmablv be provided with portions adapted to receive hammer blows, whereby said wedge member ma be. driven into wedging relation with its adjoining parts or moved from wedging relation therewith.

Certain contractors prefer to use shores having a rigid abutting relationship between the slide and its supporting member. The present invention is narticularly useful in this way. Figure 7 illustrates a slide 15 having secured thereto, on its front side, an elongated metal plate 35 having recesses 36- 36 for receiving the ribs 2828 of the gripping member 2t. The metal plate 35 ma be applied or removed without the exercise of any great amount of skill and has the advantage that the ribs 2S--28 of t metallic gripping member 28 in v2 a po 1 tive abutting relationship with the metalli plate 35 in the recesses thereof. It will b understood. of course, that instead of having ribs on the plate 26 and corresoondinn' reccsses on the plate 35. the plate may be provided with the ribs and the gripping memher 2''? provided with the corresponding recesses.

The mode of operation of th pr sent invention will be c ear without detailed description. It may b stated briet v, however. that with the wedge member 130 loosened from wedging relation with its cooperating parts the slide 15 may be raised relative to the standards 10-l0 to approximatelv the position required for the top or": said slide 15. The top portion of the wedge member 30 may then be struck a blow in a downvard direction whereby sa d wedge member 30 will force the gripping member 26, including the ribs 98 thereof, into firm gripping relationship with the slide 15; or in case the plate 35 being used the wedge member 30 will hold the rios o't gri 'iping member 26 in firm gripping engagement with the recesses 36 St) in said plate 35. Turning movement will then be applied to the bolt 22 to con'nnunicate a lifting movement to the slide 15 to bring the top thereof positively and accurately to the desired level.

Particular note should be made of: the fact that the full gripping etlect between the gripping" member 26 and the slide 15 is accomplished before the load is applied to slide 15 the advantage being obtained that. there is a minimum tendenc ot the slide 15 to slip from its adjusted posi ion unde load.

When it is desired to release the shore from its holding position. it is onl necessary to give the lower portion of the wedge member 30 a blow in an upward d rection to release the wedging relationship between the vedne member 30 and its cooperating parts. A relativel light blow will allow the slide 15 to tall :1 'l'ew inches. The wed re member 30 will. under the influence of gravity. fall to wedglng relationship with the side 15 bet'ore the slide 15 will have had a chance to travel tar. The danger is obviated. thcretore. that the slide 17 will drop with a SUtTlClPH jar from its upper position to a position at the base of the standards 1010.

The present invention combines the advantages :bove referred to with the advantape that the slide 15 may be embodied in any ordinary timber such as is commonl; found in the equipment of building con structors. It will be noted that the wedgingz action between the gripping member 26 and portion 18 is substantially transversely of the slide 15, whereby tendency of slide 15 Ill to get out oi proper alignment is minimized.

Though a preferred embodiment of the present invention has been described in detail, many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the invention as defined by the appended claims.
